Table 1: Rack Requirements and Specicaons for an MX204 Router (Connued)
Rack Requirement Guidelines
Rack size and strength
• Ensure that the rack is 19-in. wide as dened in Cabinets, Racks, Panels,
and Associated Equipment (document number EIA-310–D) published by
the Electronics Components Industry Associaon (hp://
www.ecianow.org/).
• Ensure that the rack is of one of the following standard depths:
• 23.6 in. (600 mm)
• 30.0 in. (762 mm)
•
31.5 in. (800 mm)
•
The rack rails must be spaced widely enough to accommodate the router
chassis's external dimensions (see No Link Title). The outer edges of the
mounng brackets extend the width to 19 in. (48.3 cm). The spacing of
rails and adjacent racks must also allow for the clearances around the
router and rack.
• The router ships with the front-mounng brackets xed in the front-
mount posion on the chassis. You can move the rear-mounng
brackets based on the depth of the rack.
• The chassis height of 1.72 in. (4.37 cm) is approximately 1 U (rack unit).
• The rack must be strong enough to support the weight of the fully
congured router, up to 22.7 lb (10.3 kg).
• Either end of the router must be mounted ush with the rack and sll be
adjustable for racks with dierent depths. The front and rear rack rails
must be spaced between 23.62 in. (600 mm) and 31.5 in. (800 mm) front
to back.
• Ensure that the spacing of rails and adjacent racks allows for the proper
clearance around the router and rack.
